l SPECIFICATION forming part `of Letters Patent No. 254,165, dated February 28, 1882.

Application lfiled December 9, 1852.1. (No model.)

To all whom t may concern: y Beit known `that I, JAMES SCHUYLER, of`y Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful Improvements in Turn-Tables; and I do hereby declare that the following is a tull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, refer- 1o ence being had to the accompanying drawings,

which form a part of this specification.

Myinvention relates to turn-tables for railroad-cars, engines, 85o.; and it consists, first, in a bed divided into two inclined planes upon which are secured the track-rails curved to lit the inclines.

It further consists in a table having two anged wheels at each outer end, two or more central unanged wheels, and a shaft or bolt 2o rigidly secured-t0 the center of the table and entering a pipe and conc in the center of the bed to guide the bed in its ascent and descent on the inclined bed.

It further consists in details ot construction that will be more fully set forth in the specification and claims and pointed out in the accompanying drawings, iu which- Figure 1 is a perspective view of my device; Fig. 2, a plan view, and Fig. 3 -a vertical section ot same.

Referring more particularly to the drawings, Aindicates the base, which may be of concrete, rubble, stone, heavy timbers, or a floor ot' plank. Upon thislay a sufficient number of ties of varying thickness to give the desired inclination divergiug from the center block, E, which may be of wood, stone, or iron. Upon these ties I spike the rails U D, which arc curved to lit the inclined sides B B,which, as 4.o shown in Figs. l and 3, are inclined planes. The center block, E, is for the support of the vertical cylinder or pipe F. These parts are intended to be stationary. Secured to the center of the table is a shaft or bolt, H, about 4`5 three inches in diameter and six feet in length, that passes downl through the vertical pipe and cone at the bottom. At each opposite end of the table G are two flanged wheels, I, travcling on the outer rails, O, and on opposite 5o sides of the shaft H are two or more unllan ged wheels, K, which travel on the central rails, D.

-These wheels are about two feet in diameter; but may be of'any convenient size, and are secured to the'table in any convenient way. The

number of wheels-may vary accordingto the length of the table. The circumference of the large circle under the table is one hundred and twenty-six feet, the diameter thirtynine feet three inches, the diameter of small circle thirteen feet one inch. The table is intended to be forty-three feet long over all, and about four feet high from the rail-circle, and the chords about four feet apart, with plank twelve feet long spiked across the top of the chords, on which the rails will be fastened that the engine will stand on while the table is carrying it around until it meets the track to run ot't on. Then the table is turned back empty to the high point to take another load around to the t,

low point.- rIhe table is adapted to turn about half a circle on each inclined plane, audits particular utility exists in shifting the load from the higher-level track to the lower-level track. The high point on each side B B will be about twelve inches above the low point, but can be varied as desired. The table G, when finished, has a iloorof plank twelveinches long by two inches thick fastened across on top of table-chords.

It will be observed that one end of each side B B is elevated above the other, and the elevated end of one side, B, is adjacent to the lower end of the opposite side, B'. At these low points I may have suitable buffers, P, to take up the force of the weighted table when it reaches the lowest or stopping point. The object of thisforrn of' construction of table and bed is to cause the wheels otl the table to travel on a descending grade when loaded and on an ascending grade when not loaded, so that when a table is loaded with a forty or fifty ton engine the weight of the load will assist in making the turn. The table is intended to belevel at any point it may be on. The planes, each of which forms a half-circle, are inclined in opposite directions, while the central portieri or block, E, is in a single horizontal plane. As the table travels from the higher to the lower point but little if any forceV isv required to move it.

The table may be-furn'irshed with suitable stop or brake mechanism, so as to stop it at IOO any desired point on the incline to meet tracks which are graded and run to conform to the level ot' the tabletracks.

Having thus described my invention, what I claim is- 1. A track-bed for railway turn-tables, consisting of tivo inclined planes, each ot' which forms a half circle and inclined in opposite directions, and provided with tracks curved and inclined with the face of the plane to which they are secured, substantially as shown and described, and for the purpose set forth.

2. A track-bed for railway turntables, consisting ot' twoinclined planes provided with an exterior and interior track, as described, and a cone and pipe secured to said bed and adapted to receive a guide-shaft secured to the cen ter of the table, substantially as shown and described.

3. A turntable provided with outer Hanged wheels and inner unflanged Wheels, and adapted to travel on tracks secured to inclined planes in such manner that the table will be level at any position, substantially as and for the purpose set forth. t

4. The combination of the bed A, having the inclined surfaces B B', tracks C D, cone F, and pipe F', with the table Gr, provided with Wheels I K, and shaft H, substantially as described, and for the purpose set forth.

In testimony that `I claim the foregoing as my own I have hereto affixed my signature in presence ot' two witnesses.

JAMES SGHUYLER.
